Abstract: 863,995. Cosmetic &c. holders. WALLER, C. D., and WALLER, D. D. Feb. 4, 1959 [Feb. 27,1958], No. 6408/58. Class 18. A cosmetic dispenser comprises a case a, at least one stem c and a follower b apertured to slide along the stem c but not rotate, the periphery of the follower b and the internal surface of the case a having screw engagement. A helical rib b<SP>1</SP> on the cup or follower b engages in a helical groove a<SP>3</SP> on the internal surface of the case a. A finger knob d is secured to the stem c and on rotation relative to the case a causes the cosmetic to be projected or retracted. To assemble the dispenser a grommet e is pushed into an aperture in the end wall a<SP>1</SP> of the casing a, an octagonal end c<SP>1</SP> of the stem c is passed through the grommet e, the knob d. is secured to the stem c, the follower b is pushed into the case a to engage the free end of the stem and retracted down to the grommet and the stick is cast in the case. In an alternative embodiment, Fig. 4, the follower 11 is provided with a helical groove 17 to engage a helical rib 16 formed on the case 10 which is surrounded by a sheath 14. The base of the follower 11 has a circular rib 32 which forms a seal against a collar 19 of the stem 12 formed with side wings 13. Fins 31a are set in the follower 11 and have a driving action on the stick to facilitate its retraction. In a modification the stem is secured to an outer sheath surrounding the case which is provided with a gripping ring. In a further modification, Fig. 10, the outer sheath 38 has opposite ribs 39 connected to the knob 40 so as to leave slots 41 through which a ring 42 can be gripped.

Title: Improvements in or relating to die-casting and apparatus therefor
IPC: B22C9/06
Filed: 1941-05-23
Abstract: 549,553. Casting-machines; moulds; jointmaking packing. O'SHEI, W. E. May 23, 1941, No. 6620. [Class 83 (i)] [Also in Group XXVI] The parts of a split die 1, 2 are sealed to prevent air leaks in vacuum casting, by casting metal into a channel 6 formed in one or both die faces around the die cavities 3. The metal for the cast article may be drawn in by the vacuum alone or pressure may also be applied to it. The metal for the seal may be cast by gravity or be forced in or drawn in by vacuum. The metal for sealing may be the same as for the cast article and may be supplied by the same or separate goose-necks. A fresh seal may be cast before each operation or a seal may be retained so long as it is effective. To prevent the seal from melting, a metal having a higher melting point may be used or the die may be water-cooled. The mould may be evacuated through the sprue 5 of a separate hole 14, Fig. 3, leading to a channel 15 may be used. The channel 15 is connected to both the channel 6 and cavity 3 by narrow passages 16 so that seal and article are cast at the same time, any metal entering the passages 16 being immediately solidified. In another modification molten metal flows around the sealing groove and from this to the die cavity. In another modification the sealing cavity is formed at the co-operating faces of a die holder surrounding the die. The Provisional Specification describes the use of asbestos in the groove for sealing and the use of different pressures when two goose-necks are used.

Title: Manufacture of products of sheet material carrying a film of gum
IPC: C09J7/32
Filed: 1948-03-04
Abstract: A sheet material such as paper is provided with a coating of gum capable of being rendered adhesively tacky by moistening with water, which, while appearing megascopically homogeneous (i.e. as observed with the naked eye, or with the aid of a small pocket lens) consists of the solidified gum having a multiplicity of microscopic air spaces therein.  It may be produced by emulsifying in an aqueous solution of the gum, serving as the continuous phase, a volatile liquid which is substantially insoluble in water and a non-solvent for the gum, applying a film of the emulsion to the sheet material, and drying to set the gum and evaporate the water and the volatile liquid, substantially in that order, to reproduce in solid form the spatial disposition of the continuous phase of the liquid film.  Examples of such gum compositions are given in which (1) "Solvesso" (Registered Trade Mark) Xylol (a mixture of dimethylbenzenes) is emulsified in aqueous solutions of bone glue, in some cases using an emulsifier, Aerosol OT, stated to be di-octyl sodium sulphosuccinate; (2) "Solvesso" Xylol is emulsified in an aqueous solution of partially converted starch, using alkali lignin as emulsifier; (3) "Solvesso" Xylol is emulsified in a solution of dextrin, using Aerosol OT as emulsifier; (4) "Solvesso" Xylol is emulsified, using Aerosol OT, in an aqueous solution of Elvanol 51 A-05, a low viscosity cold water soluble polyvinyl alcohol; (5) Varsol No. 2, a petroleum solvent having a boiling range of about 305 DEG  to 397 DEG  F., and a flash-point of about 110 DEG  to 114 DEG  F., is emulsified, using Indoil Sulphonate B, Purified, a petroleum sulphonate, in a solution of Rhotex size, stated to be a polymerized sodium acrylate; (6) Varsol No. 2 is emulsified, using Indoil Sulphonate T-16, a petroleum sulphonate, in a solution of Methocel, a methyl cellulose of 25 centipoises viscosity; (7) "Solvesso" Xylol is dispersed, using alkali lignin, in a solution of gum arabic. Other volatile liquids which may be used are methyl hexyl ketone, diphenyl ether, o-dichlorbenzene, solvent naphtha Nos. 3 and 6, butyl acetate, cyclohexanol and carbon tetrachloride.  The compositions were coated on paper in accordance with usual practices, and the products dried, first at room temperature and then on a drum heated to 220 DEG  F., but similar results are obtained by drying throughout at 140 DEG  F., or at room temperature. Attainment of the final porous condition is indicated by the coating acquiring an opaque, white, glossy appearance.

Title: Process for the hydrogenation of carbon monoxide
IPC: C07C1/04
Filed: 1953-03-13
Abstract: Hydrocarbons and oxygen-containing organic compounds are obtained by the hydrogenation of carbon monoxide at 150-350 DEG  C. and 1-200 atmospheres pressure in the presence of a fused or sintered iron catalyst containing more than 20 per cent by weight of copper relative to the iron, the catalyst having been reduced at a temperature not exceeding 350 DEG  C. before use (see Group III). Hydrogenation temperatures of 180-270 DEG  C. and pressures of 10-50 atmospheres are preferred.  Feed rates of 10-1000 vols. of gas per vol. of catalyst per hour, and CO : H2 mol. ratios of 1 : 0.5 to 1 : 5, may be used; the product gas may be recycled.  In multi-stage operation, carbon dioxide may be removed between the stages.  When a product containing a large proportion of high boiling-point esters is desired, the catalyst has more than 80 per cent of the iron in the metallic state, a copper content of more than 25 per cent, and an alkali metal content of 6-10 per cent; for the product to contain a high proportion of alcohols, the free iron content is 20-80 per cent. When the alkali is present as potassium silicate, the proportion of high molecular weight hydrocarbons in the product increases.  The catalyst may be used as a fixed bed or in the fluidized state. Reduction of the catalyst may be effected in the reactor, under normal, increased, or reduced pressure, using a gas containing hydrogen and/or carbon monoxide.ALSO:A fused or sintered iron catalyst for the hydrogenation of carbon monoxide (see Group IV (b)) contains more than 20 per cent. by weight of copper relative to the iron, and is reduced at a temperature not exceeding 350 DEG  C. before use.  When a hydrogenation product containing a large proportion of high boiling-point esters is desired, the catalyst has more than 80 per cent. of the iron in the metallic state, a copper content of more than 25 per cent., and an alkali metal content of 6-10 per cent.; for the product to contain a high proportion of alcohols, the free iron content is 20-80 per cent.  When the alkali is present as potassium silicate, the proportion of high molecular weight hydrocarbons increases.  Iron and copper in the metallic state or as oxides, in the form of a powder or lumps, are heated together at a temperature of, e.g. 1,150 DEG -1,600 DEG  C. in an oxidizing atmosphere; for sintered catalysts the starting material should preferably have a particle size of below 100m ; the mixture may p include promoters such as oxides of chromium, manganese, aluminium, calcium, titanium, silicon, or zinc, and oxidizing agents such as nitrates, nitrites, or perborates.  The mass is cooled in air and crushed to the required size.  Reduction may be effected in the synthesis reactor, using a gas containing hydrogen and/or carbon monoxide under normal, increased, or reduced pressure; gas velocities of 50-150 cm. per sec. may be used at atmospheric pressure or 5-40 cm. per sec. at superatmospheric pressure; the gas used preferably contains less than 0.1 gm. of water vapour per cubic meter.

Title: Improvements relating to the catalytic conversion of hydrocarbons
IPC: C10G11/18
Filed: 1945-03-20
Abstract: Hydrocarbon oils boiling above the gasoline range are mixed with 20 per cent to 40 <PICT:0601679/III/1> per cent by weight of steam, or an equivalent molecular proportion of other inert diluent gas, and the mixture is contacted with an acid-treated bentonite clay, a synthetic silica-alumina gel or a synthetic silica-magnesia gel, in a reaction zone at a temperature between 970 DEG  F. and 1050 DEG  F. Nitrogen, carbon dioxide, or oxygen-free combustion gases are preferably used in place of steam when silica-alumina gel is used as catalyst.  High octane gasoline and good yields of butylenes are obtained by the process.  The feed stock may comprise heavy naphtha, light gas oil, heavy gas oil, wide range gas oil, reduced crude oil, or topped crude oil.  The feed, preheated if desired, is introduced through line 10 and mixed with the steam or other diluent gas, which is added through line 26.  Hot regenerated catalyst particles at 1000 DEG  F. to 1150 DEG  F., in an amount sufficient to raise the mixture to reaction temperature and to supply the heat of cracking, are fed into it from standpipe 12.  The mixture passes into reactor 17 where a temperature of 970 DEG  to 1050 DEG  F. and dense phase conditions are maintained.  If desired, the diluent gas may be introduced at the bottom of the fluidized bed 22.  The reaction products pass through separator 32 to a fractionating system for separating gasoline and desired gases.  Contaminated catalyst is withdrawn from the body of reactor 17 through zone 42 where it is stripped of entrained hydrocarbons by steam, carbon dioxide, or nitrogen introduced through lines 44.  The stripped catalyst passes into standpipe 46 controlled by valve 54 which is used to adjust the level 24 of the dense phase. The catalyst is then mixed with oxygen-containing gas from line 56 and the mixture introduced into regenerator 64 where dense phase conditions are maintained.  Hot regenerated catalyst is withdrawn from the regenerator through trough 84 and standpipe 12, and is controlled p  by valve 94 which is also used to adjust the level 72 of the catalyst in the regenerator.  Specification 332,285, [Class 32], is referred to.

The radiation-producing fluidic material used in the testing method of the parent Specification is such as to produce primarily low-range nuclear radiation, the retardation of which, by the body under test, produces electromagnetic radiation of highrange. A suitable radiation source is krypton 85, which produces high-energy beta radiation, and it is preferred to use a mixture of one part by volume of krypton 85 with a hundred parts by volume of nitrogen. The method is used in testing for leaks in a body, as the parent Specification. The body is immersed in the fluidic material, which penetrates into any leaks, and the external surface is decontaminated. The retardation of the beta radiation by the body produces high-range electromagnetic radiation which penetrates to and beyond the external surface of the body, while the beta radiation itself does not so penetrate.
